Mar.30 (GMM) Fernando Alonso was unimpressed with the performance of his KERS system in Sunday's Australian grand prix.

The Spaniard was one of just seven cars fitted with the controversial new energy re-use technology in Melbourne.

"It was not very useful," he told Spain's AS sports newspaper. "In terms of laptime we knew it doesn't give us an advantage, but I used it when I was right behind Glock - without a KERS - and the truth is that it was no help at all.

"At this circuit there was no benefit. But let's see what happens at tracks with very long straights, like Bahrain, or Monza," the Spaniard added.
